PURPOSE:To obtain a stacking unit of simple structure which allows bagged loads etc. to be stacked to a certain height as well as in good order by providing both an upper slider which makes loading work at a certain height and a lower slider which lifts the loads up to the certain height, in such a manner that they can slide and move freely with respect to a piece of hollow column. CONSTITUTION:In loading work, when a load 48 is conveyed onto a load table 45 from a belt conveyor 47, a photocell 50 detects it and operates a vibration- conveying means 46 in order to shift the load 48 to a certain position on the table 45. Then a lower slider 6 is elevated by a motor 36 via a chain, and a comb-lever 31 supporting the load 48 is also elevated. When the slider 6 is stopped at its upper limit, holding levers 20 and 20' of an upper slider 5 which have been waiting at the limit position, close to hold the load 48. Thereafter, motors 9 and 12 operate to properly rotate a main arm 8 and an auxiliary arm 14 to give the load 48 a selected orientation, then the holding levers 20 and 20' are released so that the load 48 is dropped on a pallet 52 for loading. |
